Authors' conclusion

NLR and MLR are potential biomarkers to predict gout flare risk. An increase in either may indicate an increased risk of CVD morbidity.

Study context

Population
Gout patients
Participants
38 patients
Exposure
High vs low neutrophil-to-lymphocyte ratio (NLR) or monocyte-to-lymphocyte ratio (MLR)
Outcome
Disease activity (total number of acute gout attacks) and 10 year risk of cardiovascular morbidity, in relation to NLR and MLR

Main finding

As reported in the abstract

Correlations of NLR and MLR with calprotectin, gout attacks and CVD risk

Odds ratio

7.5

95% CI 1.7–33.0

High NLR or MLRvs Low NLR or MLR
OR 7.5 (95% CI 1.7–33.0)
Calprotectin correlated with NLR
r = 0.56, p = 0.0004
MLR correlated with total number of gout attacks
r = 0.39, p = 0.02
NLR and MLR, but not absolute monocyte or neutrophil counts, significantly correlated with BMI and significantly increased in patients with high cardiovascular disease (CVD) risk
P < 0.05

Observational data: associations, not effects.
